REFRIGERATOR.

- of which the following is a specification.

My invention consists of an improved refrigera'tor. to provide an improved refrigerator of the type which has chambers provided with front doors, said doors permitting the insertion of ice and food into their respective chambers.

' Another object of my invention is to pro vide means within the refrigerator which will cause ,the air, chilled by the ice, to be purified and to be directed in an unobstructed path into the provision chambers and then back again to the ice.

A further object is to provide improved means whereby the vapors, moisture, and impurities will be readlly carried ofl with the drain water from the melting ice, leaving pure, dry, and extremely cold air to passin an unobstructed volume to'the provision chambers.

A stillfurther object is to so construct my improved refrigerator that .it will not contain any gutters or crevises thus avoiding the accumulation of slime or dirt.

Another object is'to so make my refrigerator-that it will be of simple construction.

and can be manufactured and sold at a reasonable cost. Another object is to so design certain o the parts that they can be easily and quickly removed for cleaning purposes.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to thewa'ccompanying drawings in Speeification of Letters Patent.

One object of my invention is Patented Jan. 22,-1d1d.

Application filedmay 1, new. Serial no. 165,664.

porting ledge for certain of the elements hereinafter described.

Flg. 5 is a view of similar nature to Fig. 4 showing the same bend to provide the corner and ledge above noted. v

Fig. 6 is a top plan view of abase plate which forms a part of my invention.

Referring to the drawings, l represents a refrigerator casing closed at the top, back, sides, and bottom, but open at the front as will hereinafter be more clearly described.

An ice chamber 2 is normally closed by. a door 3. This ice'chamber is in communication with a chamber 4, directly below it, said chamber generally being used for the storage of milk and butter and closed by a door 5.

A large vertically extending chamber 6 is separated throughout aportion of its length by a partition 7, and said chamber 6 is in communication at its top with the ice chamber 2 through the medium of a passage 8. The chamber 6 is also in communication with the chamber 4 through the medium of a passage 9, so that air circulates downwardly through the ice chamber 2, chamber 4, passage 9, and thence upwardly through the chamber 6 and passage 8 into the ice chamber 2. The chamber 6 is a normally have inwardly bulged portions 14. These bulged portions are formed by cutting angular recesses 15 as clearly shown in Fig. 4, so that the sides and rear wall can all be made in one piece without an seams.

The top 16 of the bulged portion 14 forms a supporting ledge for the. flange 17 of a frame 18, this frame having a depressed portion19 which is open at its bottom and provided with an internal flange 20 designed to form a support for a corrugated base plate '21,-the latter having a plurality of perforations 22 as clearly shown in Fig. 6. The front wall 23 is also preferably made integralwith the side walls 12 and 13 and the top art 28 of its bulged portion is extended orwardly to provide a reinforcing facing 29 directly below the door 3.

. ter with said hole 32. A drippipe 34 is se-.

cured within the casing 1 and is'of larger diameter than the spout 32 so that the latter can slightly telescope the same. The lower end of the drip pipe 34 extends below the bottom 35 of the casing (see Fig. 2) and a pan may be placed below the'drip pipe to receive the drip water passing therethrough.

Sheds 36 and 37 are preferably made of sheet metal and slant toward the tray' 30. The ends 38 of the sheds 36 and '37 are secured to the straps 31 and extend directly over said tray 30. The sheds 36 :and 37adjacent their opposite ends are secured'by' straps 39 to the frame 18. I preferably extend the ends 40'of the sheds 36 and 37 beyond the outer surface of the depressed portion 19 of the frame18 so that any moisture which collects thereonwill drop onto said sheds. Q

It will thus be noted that the sheds 36 and 37.are interposed between the bottom of the frame 18 andthe tray 30, so that-air. currents are free to pass downwardly through. the perforations 22 in the base plate 21, and

downwardly toward the tray 30, coming in contact with the drain water-so that any impurities will be absorbed by the-water and carried out through the medium of the tray 30, spout 33, and drip pipe 34.

A deflector 41 is secured to the sideand rear walls of the chamber 2 and has an ularly disposed portions 42 and 43 on the side walls, and an angularly disposed portion 44 on the rear wall. The portions 42 and 43 slant downwardly, as clearly shown'in Fig. 2, toward the rear of the chamber 2'which permits the frame 18 together with its connection to be raised and removed through the front of the casing when door 3 is open. However, the portions 42 and 43 extend sufficiently far on the inside of the chamber 2 that any moisturewhich collects on the walls, will run down the upper surfaces, from thence it will dro into the frame 18, and eventually to the s eds 36 and 37 and deflector 42 will serve to de ect any moisture running down the rear wall 11, into the frame 18, and eventually into the tray 30. through the medium of the sheds 36 and 37. Thus with my improved refrigerator, the air chilled by the ice can freely circulatein coming in contact with the deflector, frame,

sheds, and tray will be absorbed by the water and carried directly to the drip pipe.

Therefore, by the construction above described, the air within the refrigerator will bekept pure, cold, and dry, thus rendering the refrigerator of particular value for householdor store purposes where various kinds of food are kept in the same refrigerator, since it will practically prevent one kind of food from being contaminated with the odor of another kind of food.

It will be further noted that by forming the supporting-ledges integral with the walls I which provide the inner lining of the casing, it will be practically free of crevises in which slime or other dirt 'cancollect. The entire frame, sheds, and tray can be removed as a unit, sufiicient room being provided between the rear flange of the frame 18 and the portion 44 of the deflector 42 to permit the disconnection of the spout 33 with the drip pipe 34.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit-thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty .tomake such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what 'I claim as new and desire to-secure by Letters Patent is: 4

1. A refrigerator including a casing having an opening inone of its upright sides, a door for closing said opening, an inner wall made of sheet material having portions bent inwardly to provide a ledge substantially on a level with the bottom of said opening, a frame supported on said ledge and having a perforated bottom, and a deflector project, ing inwardly from said wall sheet and having side portions extending at an angle downwardly on the side walls from portions adjacent said opening to the rear portion of the wall and across the rear of. said wall, substantially as escribed.

2. A refrigerator including a casing having an opening in oneof its upright sides, a door for closing said opening, an inner wall made of sheet material having portions bent inwardly to provide a ledge substantially on a level with the bottom of said opening, a frame supported on said ledge and having a" perforated bottom, a deflector projecting inwardly from said wall sheet and having side portions extending at an angle downwardly on the sidewalls from portions adjacent said opening to the rear portion of the wall, sheds supported below said bottom of the frame and at opposite sides of the center thereof, and a water con ducting tray supported below said sheds, said deflector being inclined sufficiently to permit the forward ends of the frame and tray to be raised into a position to be bodily slid out of said opening in the casing, substantially as described.

3. A refrigerator including a casing having an angular interior and an opening in one of its upright sides, a door for closing said opening, an inner Wall made of sheet material and being continuous around the angular portions of the 1nter1or of said casing, said wall having integral bulged portions extending along the sides and back and located at a position between the top and bottom of the casing and providing a ledge at a level adjacent the bottom of said opening, and an ice supporting frame adapted to rest upon said ledge, substantially as described.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses. I
